Mac 10.11.3 AppleHDA/Realtek ALC668 Issues

Hello!

 

I'm running macOS 10.11.3, and I'm experiencing a rather odd issue with AppleHDA and my system's audio.

 

The system appears to be detecting the card, and it knows it's an audio device. However, it doesn't show it as a usable output device. (http://i.imgur.com/ksWmCkO.png) Similarly, the input device doesn't show up.

 

I'm using a patched AppleHDA (attached) and my AppleHDA clover config is below:

<key>Audio</key>
<dict>
	<key>Inject</key>
	<string>3</string>
</dict>

Is there anything I can do to solve this problem (preferably through the use of Clover only so it persists through updates)?

 

If needed, I can attach my codecs and similar if a re-patch is needed.

 

I have no DSDT patches for codecs or Layout IDs.

I have tried patching the layout ID in all possible places (one at a time, of course):

 

- DSDT

- Clover config.plist

- HDAEnabler

 

All of these return the exact same result: the devices are detected (with the right layout ID), but they can't be used for some reason.

 

My IOReg returns two (?) entries for PCI0\AppleACPIPCI: HDEF@3 and HDEF@1B. You can see these in this screenshot. I would assume one of these is the HDMI on my laptop (Intel 4400), which I have not yet tested.

 

If needed, I can PM my entire IOReg to anyone interested.

Edit: Upon installing AppleALC, the system is detecting everything and it shows up in my Settings menu. However, sound still refuses to play. The microphone does work. I'm even more confused than before.
